The AUTOERASE Control Option must be set to (ALL) for all systems.

Overview

V-190	TSS0270	SV-190r3_rule	DCCS-1 DCCS-2	Medium

Description
AUTOERASE will force TSS to erase all residual information on DASD. The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during migration process or contingency plan activation.

Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(STATUS) Automated Analysis requiring Additional Analysis Refer to the following report produced by the TSS Data Collection: - PDI(TSS0270) If the AUTOERASE Control Option value is set to ALL, this is not a finding.

Fix Text (F-16737r3_fix)
The IAO must ensure AUTOERASE control option is set to (ALL) for all systems to erase all residual information on DASD. Evaluate the impact associated with implementation of the control option. Develop a plan of action to set the AUTOERASE control option to (ALL) for all systems and implement.
